Hey there! If you've got our 3D floor murals, here's how to use them. First, measure your room to know how many square meters you need since our price is for 1 square meter. Next, pick a place on the wall or floor and wipe it clean. Hold the sticker in your hand to see the best way to apply it to make it look great. Then, start from the bottom of the paper and lift the sticker. Stick it starting from the middle and go towards both ends. These murals are waterproof and wear - resistant, which is really handy. And they have seamless splicing. Just a heads - up, because of monitor settings, the color on your screen might be a bit different from the real thing. When it comes to maintenance, since they're waterproof, a simple wipe with a damp cloth should do the trick to keep them clean.
